How to unlock PIN code lock and firmware lock on this MacBook Air?
As we know, there are several reasons for forming a PIN code:
- MacBook ID password stolen,the other side can remote login through our ID, directly set a password to the MacBook, which is called the PIN code,
- The user set a PIN code on the MacBook, but the user forgot it
- Accidentally set up a PIN code by manipulating the MacBook in a random manner
When the PIN code appears, restart the MacBook Air, and then hold down the ALT (Option) button before the screen lights up. When the MacBook screen is lit up, you will see the firmware lock interface.
The firmware lock we're talking about is actually the motherboard password (hardware password), it can't be removed by reinstalling the system. The password for the firmware lock is in the BIOS chip that exists on the MacBook motherboard. To unlock it, we need to read the data inside the BIOS chip, and then use proprietary software to remove the inside password, and then re-write information to the BIOS chip.
Because generally the BIOS chip is on the backside of the MacBook motherboard, it's complicated to remove it to read and write, so we can use special tool to read and write BIOS information without removing the MacBook motherboard.
Run ZXW Dongle, open the bit map to find the BIOS chip, find the connection point that's connected to the BIOS chip 8 Pin VCC, it should be under the motherboard.
Based on the MacBook bitmap, we know that the 1 Pin for R8133 is connected to the BIOS chip 8 Pin. Put MacBook motherboard under the microscope, connect the external BIOS chip to the power 3.3V to this resistor 1 Pin.
And then find SAM connector 1 Pin.
Find the SAM connector on the bitmap, the first pin for this connector is grounding, we can use digital multimeter to measure the first pin. Connect the corresponding interface, the other side connected to the programmer, external plus a BIOS chip power supply 3V-3.3V voltage.
The programmer will automatically recognize the BIOS chip model, and then read the information for the BIOS chip, and then save the original BIOS information. Open the special unlock software to remove the password for the BIOS information, and then re-write the information to the BIOS chip.
After successful writing, remove the unlock tool. Supply power to the MacBook Air, press the power button, and then hold on the Option, Command, R and P button at the button, which is to clean the BIOS. Release those buttons after the MacBook automatically restart.
Now the MacBook Air enters systems normally, press the Option button when booting, there is no lock, the MacBook Air has been unlocked.
